    BOOTP AND DHCP PARAMETERS

    The Bootstrap Protocol (BOOTP) [RFC951] describes an IP/UDP
    bootstrap protocol (BOOTP) which allows a diskless client machine to
    discover its own IP address, the address of a server host, and the
    name of a file to be loaded into memory and executed.  The Dynamic
    Host Configuration Protocol (DHCP) [RFC1531] provides a framework for
    automatic configuration of IP hosts.  The "DHCP Options and BOOTP
    Vendor Information Extensions" [RFC1533] describes the additions to the
    Bootstrap Protocol (BOOTP) which can also be used as options with the
    Dynamic Host Configuration Protocol (DHCP).

    BOOTP Vendor Extensions and DHCP Options are listed below:
